Hand operated sampling valve (referred to as Tank valve, Angle bottom valve, Bottom drain valve, Flush mount valve etc) are designed to provide tank drainage and sampling free shut off for reactors, vessels, autoclaves and storage tanks. Rising disc type means that the valve is opened into the tank .
The sampling valve is designed with Y-type. According to the actual operating condition, the dumping entry has two types: pipe-connecting and flat bottom. If needed ,special surface treatment on the whole valve makes the surface hardness more than HRC 60, this can ensure the sealing reliability and avoid scarring.
Moreover, a rotation-resistant device is set to ensure that the valve stem only has straight line motions, and no revolving motions. The driving manners of the valve include hand driving, electric ,driving, pneumatic and gear driving. Both rising disc type (the valve is opened into tank) and lowering disc type (the valve is opened into valve) can be designed.
BENEFITS
1.The valve is designed as piston type ,can meet the requirement of full flow condition ;
2. The disc is designed as the same as valve size ,and the valve is on-off by up and down moved .As piston and tank bottom are in the same horizontal position when the plug stretch out ,the material is not easy to stuck on.
3.Both lowering disc type (the valve is opened into valve)and rising disc type (the valve is opened into tank) can be designed if needed.;
4.As the disc is moving up and down ,it clean the valve inner body ,so sampling valve suitable for slurry medium .
5.The sealing surface of the valve seat and the valve disc is made of over laying cemented carbide or painted with tungsten carbide. The auxiliary line sealing guarantee the reliability of the sealing performance.
